Here's our preferred bonnie++ command line:

- /usr/sbin/bonnie++ -r <ramsize> -s <twice ramsize> -x 1
+ /usr/sbin/bonnie++ -n 128
-r <ramsize> -s <twice ramsize> -x 1
</verbatim>
Some documentation suggests that you should use about 40 times the ramsize in your -s parameter, as opposed to 2 times the ramsize. This will obviously take longer, but should sidestep any cache improvements you might see which could influence your results. If you change your bonnie++ command line please make a note of it

Please make a note of your system specification, in particular the disk IO subsystem, which OS, and which version of bonnie++ you are running.
+If you get all +++++ results for the Create tests your disks are too fast to test. Meaningful results require the test to take longer than 500ms, increase the number of files used for the test with the -n commandline option.
